Routing Verdict & Tradeoffs

Ethen Routing Verdict

Frontier research / complex reasoning

Claude 4.1 Opus (Reasoning) scores 34 (estimated) on the Artificial Analysis Intelligence Index, placing it above average among other reasoning models in a similar price tier (median: 28). Claude 4.1 Opus (Reasoning) generates output at 33.3 tokens per second (based on Anthropic's API), which is at the lower end compared to other reasoning models in a similar price tier (median: 81.2 t/s). Claude 4.1 Opus (Reasoning) costs $15.00 per 1M input tokens (at the higher end, median: $1.50) and $75.00 per 1M output tokens (at the higher end, median: $8.40), based on Anthropic's API.

Reserve this model for the hardest requests; simpler or repetitive work should stay on cheaper routes.

Task Fit Assessment

WorkloadRatingNotes
Complex reasoning & agentic workflowsoptimalIntelligence score 34 places this model among top performers. Suitable for multi-step analysis and agentic loops.
High-volume chat & customer-facingviableOutput speed may be a bottleneck for real-time chat at scale.
Latency-sensitive applicationsviableTTFT 15.46s — latency may be noticeable in interactive use.
Cost-sensitive pipelinesviableOutput pricing at $75.00 is premium. Route high-volume simple tasks to cheaper alternatives.

Cost Pressure Analysis

High

Pricing is premium — input $15.00, output $75.00. This model is expensive for high-volume or output-heavy workloads.

Cheaper substitutes: Lower-cost models for repetitive or high-volume work, Cache-backed reuse for repeated prompts
